, This invention relates to windows,y and more particularly to windows `of the type 1n whlch the saslrls'izmunted to turn on verte cal pivots. T le invention contemplates the n'x'iprovc- `men`t of wind the means for ows of this type in respect to msuringa close fit of t 1e sash sash in either open or closedl position', and

'fliigfis a `detail viewin 'elevationof the liftf arm and the socket formed in the sash to receive the 'lifting arm when the sash opens outwardly; Fig'. .9 is a detail view on a plane corresponding to the line 2-2 of Fig. 1, but showing a modificationof the fastening device at the upper margin of the sas'h. i

Described 1n general terms, a windoav constructed in accordance with the present invention com rises a frame, a sash pivotally mounted in tlie frame, preferably at one Side, f and susceptible of a limited vertical moveu u ment 1n re ation to the frame, a'hftmg mechanism whereby the sash may be raised and lowered through its limited range of vertical movement, and fastening dcvicesfor secur- 'in'g the sash-in open orclosed position which are made operative by lowering the sash.

` In the drawings, 1 designates the frame of the window and 2 designates thelsash, which is ol such length that a certairilI vertical movement of the sash in the frame is permitted. The frame comprises a' sill 3, side standards 4 and head piece 5. A groove `6 is-formed in the sillto receive the lower margin of the sash and is preferably of the cross section illustrated inFigs. 2 and 2^, the side of the groove toward which the sash swings in closingv being vertical and the opposite side l being` inclined. The sash is -hinged or pivoted at one side, hinges 7 being shown in Fig. '1. These hinges are so conn structed that sullicient `vertical movement of the sash teclear the groove 6 is permitted. To facilitate the lifting oil thesash out of the groove in the sill, lifting lmechanism is proi videdy en the windovt fr `me adjacent "to the "l'ra1,\ie,-an`d having` a laterally projecting lug 49," a pair of spaced'lugs 10. fixed on the sash between which the lug 9 on the rack-bar ex; "tends, and a pinion 11] for operating therac'kl bar, this pinion being provided with a lever ,the action of ythe pinionvv may be made effectL "irni12 forturning it. Two lugs 10, are proi fvidedon the-window frame in order that the downward movement of the rack-bar under `ive to force the sash ositively'downward so as tOffinsure a close tin .the groove of 'the vrwindowsill, or so as `to insure ppoper engagenent of the sash fastening devices by which the sash is secured'in open position.A

. clined plane parallelfto the inclinedfside' of the groove 6 in the window sill. To hold the top of the sashsecurely, a plate bearing a pin 16 is mounted on the head piece otthe window frame, as best seen in Fig.,2,4 and an apertured plate17 is mountedon the sash in suitable-position to engage with the pin 1G.

s To make the window Weather-proof a number of structural features are provided. A Wide bead 18 is provided on the head piece of the frame to formv an. abutment against Which the upper margin of thesash lies when closed; and asmaller bead 19 rises from the sill in front of the lowerrnargin of the sash and the abutment 14 extending along the side standard of the frame'against which the sash closes is formed with a plurality of rab- 4bets and a V-shaped groove to cooperate with corresponding formations along the free vertical margin of the sash. The V- shaped groove in the abutment on the window frame and the correspondinir V-shaped bead 20 on the sash form a specia feature of so construction by which compensation is made for expansionl and contraction of the sash or frame of the Window.

It Will be noted that a certain amount of clearancel is provided between the nonabutting surfaces of vthe rabbets formed on the abutment .ieee 14 and the adjacentA stile of the sasli, so that expansion of the sash or contraction of the window frame can take place within certain li iits without causing the sashto bind. W en 'either-of these phenomena occurs, one face of the bead 2() will always contact with the adjacent faee of the groove. lVhen the sash contracts or the frame expands, the other face of the bead will contact with the side of the groove adjacent thereto. Consequently,

Whatever change occurs in the relative sizes of the sash and frame,-With in certain limits, is Withouteffect upon the contact of at least one face of the bead 20 with the corresponding surface of the groove.

. The means employed forsecur'ing the window 4 frame in open position comprises a socket plate-21 mounted on Ithe sill and provided with a plurality. vof suitably placed sockets 22 which are provided to receive aV pin 23 provided in the lower margin of 'the sash. The'operation of this fastening device will be obvious from ,the drawings and the foregoing description. When the'sash has been raised and swung open to the desired' extent, the lever arm 12 israised and the sash is allowed to descend under theinfluence of gravity untilthe pin 23 enters one of the sockets in the plate 21.. When n'ecesstile of the sash.

ward by engagement ot' the lug t) on the rackl sary, the sash can he l'oreed positively downl i amount olI vertical movement ol' the sash. The lower pivot 2o is slidably mounted in a chamber 27 formed in the sash near its ylower margin and is provided with a lug-28 psa-sh adjacent to the side standard of the i frame. .This slidable pivot pin 26 engages a socket 29 in the sill, from which it may be disengaged by simply raising the pin within the recess in which it is mounted. The raisin-g oi' the pivot'pinl is easily eileeted by means of the lug 28 which is continually accessible in. the slot formed in the stile ol' the sash. lf it is desired to have the sash open outward, it will be found convenient to make use of the pivot pins l'or securing the sash in the window frame and the rack-bar must be )rovided with a lug 9 which isconsiderably longer than the lug 9 illustrated in Figs. 1 and 4.A f into a socket 10. formed inthe adjacent The stile of the sash is so 'l'orined that the end of the lug 9 will engage with the socket or recess lOa'in all positions oi' the sash. 'lhe extreme open position of Fig. 7, and it will beseen that the lug 9 lies in the recess l0 in all )ositions of which the sash vis susceptible'. lVhen the sash is arranged to open outwardly, the form ol' the abutment on the window frame and the. corresponding formations ol' theV sash stile are varied somewhat, butv the equivalent oi' the bead 20 is preferably retained in the bead 3() which is formed on the side standard of the stile voi' the sash.

In order to secure a wedging action in the fastening at the up er free corner of the sash, the structure siown in Fig. 9 is e1nployed. This consists in a block 31 in lieu ,of the pin 16, the block being provided with .a wedging faee'inclined i-n a plane )arallel to the inclined side of the groove in the sill and coperating with the corresponding inclined face lin the engaging plate 17a.

-lfVhile the linvention has been described Aand illustrated as embodied iii a single sash window, it will be 'obvious that it is' equally character, the free edge of oneuef the sashes will present the structural features which and ol' suiiicient depth to permit the required This lug 9 is curved and extends thesash lis indicated by dot and dash lines inframe .and engages a suitable.' groove in the applicable to' a. double Window having the frame and meetingattheir free edges. `When the 'i Fig. 6. The upper pivot 24 is tixed in the Vll() labats. For the purposes of this invention, therefore, it is irnmeterielv Whether these structural featu'res are presented by one Vside y 0f the Windowfframe' or 'by one side of a sash.

Having` thus described our inventiolln what we claim as new'and desire to secure by Letters Patent, is: l

The combination in a', Window, 0l' :L i'remef y anoutwerdly swinging sash mounted therein and having limited slidingnioveinent relatively thereto; onev of the Stiles ol said'sash l having a, curved eeess therein'sbstentially V I concentri t0 the axis'- of movement of thel I sash, amd'sJ lifting lug eo erating with said 5 recess and adapted to sli e the sash in any l l relative position of sash and frame. Y

l In testimony whereof, we have signed our Ai names in the presence of two witnesses.
